McCain packs town hall

— From NBC's Bethany ThomasPeterborough, N.H. -- The place is so packed here for McCain's 100th town hall in New Hampshire that police have stopped letting people in. About 450 people are filled into the downtown townhall. Many stragglers stand outside, trying to listen. When "The Straight Talk Express" rolled up, about 100 people were waving McCain and Irish for McCain signs, and yelling, "Mac is Back." It's rare to have more than a handful of people waiting for the bus and even rarer that they have signs.
